T 0 all whom it may concern:

lie it known that l, FIH'JDERICK L. NAY, a. citizen of the United Suites, residing at Vaeaville, in the county of Solano and State of California, have invented new and use,- ful Improvements in'Automatic Changehlaking ll-iachines, of which the following is a specification.

My invention relates to change making machines, and especially to machines for making change automatically by simply pressing a key or keys indicative of the amount received, and pressing another key or keys indicative of the amount of sale or purchase.

The invention consists of the parts and the construction and combinatioi'i of parts as hereirnitter more fully described and claimed. having reference to the accompanyin; drawings, in which-- Figure l is a perspective View of the apparatus with portions broken away to show certain parts of the internal mechanism.

Fig. 9 is a diagrammatic plan View of the so lective mechanism indicative of the amount of purchase. Fig. 1b is a plan view of the means for automatically restoring the seve al selective nn-chanisins to initial position.

A rcpt-Rents a suitable containing cabinet which may be of'any appropriate size or design, and made of any desired material. This cabinet or casing houses all the operative parts of the device, except the keys and levers necessary to be acted on directly by the operator for producing the desired results.

When the device is set up and ready for use the only working parts exposed, are, the setting key 2, (Fig. l), the releasing key 3, the upper bank of keys 4 representing the amount received the lower bank of keys 5 representing the amount of sale orpurchase keys; and the operating handle 6 by which the difference between the sum total of the keys 4 which are pushed in and the sum total of the keys 5 which are pushed in, is paid out. y

The amount of coin in the machine for change making purposes, is contained in a series of magazines 7 which are of appropriate shape, and sufiiciently numerous, and .of snflicient capacity to meet the requirements of the machine. These magazines are preferably constructed, as shown in Figs. 1, 5 and 7 of the drawings, and particularly in Fig. 1, to hold the coins on edge, one above the other, Without any danger of the coins overlapping. 'Thesc magazines may extend upward and be protected by a heavy glass front, through which the condition of the coin supply in the magazines may be readily discerned. The magazines are open at the top so as to be easily replenishedfrom time to time, and the discharge of the coins from these magazines is accomplished by certain selective mechanisms controlled by the keys or push buttons 4-5, and which selective mechanisms form essential features of the present invention.

By reference to Fig. 1 it will be noted that: there are two banks of keys 45; the bank 4 as before stated, indicating the amount received, and the bank 5 indicating the amount of sale or the amount of purchase There may be any number of keys in each bank and they will be appropriately designated "according to the national 1nonetary system, and accordin to the amounts of change to be made. T to keys 4 of the cash received series run progressively from to 20, thus; 5c 10, 25, o 50 17 as a $2 a, $3 a, ct $4 a, at $5 7: $10, $20. The lower bank of keys 5 representin the amount of sale runs progressivey thus; 10, 10, 5"

til

LC 7, C 77, 7, l 5 K 7!, L $10, There are two 10 keys in the amount of sale bank at the left and the 5 key follows third. This is merely for the matter of simplicity in the internal working parts of the machine and for making change. There are also two $1 keys, on account of the condition arising in the actual making of change.

Vlhile this machineis not designed to pay larger amounts than $20 nor smaller amounts than tie, it is manifest that the device can be readily adapted to any minimum or maximum amount. The magazines 7 are adapted to have their coin controlling devices operated upon by one or more of either bank of keys 4-5. As shown in Fig. 1, these magazines progress from left to right. as follows: 10 S 5 5 i "K H o 50 :1, :4 $1 cc $1 :7 :4 $1 a, a $1 a $5 $10. The magazines necessarily correspond to the denominations of coins minted, and there are a plurality of 5a magazines and of $1, magazines. because of the frequency with which such coins are paid out, and a single magazine for either denomination would not hold enough coins in the first place, and in the second place a plurality of magazines for these denominations is necessary to meet the exigencies in making change. For example, the purchaser is handed $5; the amount of the purchase comes to 30, delivered to the purchaser by a single actuation of the machine, it is necessary for the machine to deliver four $1 pieces, a 50 piece, a 109 piece, and two nickels, or $4.70. This of course requires four $1 magazines to deliver the The manner in which the delivery of the change is effected will he more readily understood later. As the mechanisms by which the coin is delivered from each magazine is the same for all the magazines, it will be manifest that the description of the connections between one of the upper banks ofkeys 4 and a magazine and one of the lower bank of keys 5 with the particular magazine will suffice for purposes of illustration.

By reference to Fig. 7 especially, a clear understanding of the connection between the keys 4-5 and the magazines 7 can easily be had. As shown in saidFig. 7, each key 4 is attached to an angular stem 8 mounted for reciprocation in suitable guides in the frame. The stem 8 has a shoulder 8 adapted when the key 4 is pushed in, to engage an angular arm 9 on a rock shaft 10. The other end of this rock shaft 10 has an angular lever arm 11 which is loosely connected by a link 12 with a spring-acuated hinged frame 13. The frame 13 is hinged to the casing at .14 and has a downwardly extending projection 15 arranged in the path of an angular arm 16 of a rock shaft 17. This shaft 17 has another angular arm 18 which arranged in if all the change is to be the path of a hump or shoulder 19 on the angular stem 20 of a lower key 5. Thus it will be seen that pushing in on lever 4 will engage the arm 9 and cause the shaft 10 and its angular arm '11 to rock. The loose connection 12, however, with the frame 13 11 without any movement of its corresponding frame 13, but this particular frame 13, which is connected with this particular key 4, will be rocked when the lower key 5 is pushed in. As will be particularly erplained short] every other frame 13 whirh lies to the rig it of the particular lever arm 11, which has been acted upon, will he rocked to the left by reason of certain link to the right and this particular lever arm 1].. Consideration of this matter of rocking these other arms must temporarily be de ferred until the mochanisn'i shown in Fig. 7 is clearly explained and the parts which are directly under the control of any two lH Vrs' -'-l--5, fully umlcr tood.

By pushing in on key 5 in Fig. 7, it will be ,manit'est that when the shoulder 19 ot' the stem 20 hits the angular lever arm 1 the other angular lever arm 16 will be rocked to the left to engage the pro 'cction 15 of the frame 13 and rock the same to the left against the tension of the spring The lower horizontal side of the wire frame 13 extends forward and is provided with an eye 23 which surround and forms a support and guide for a pin 24 which is hinged to the upright arm 23 of an angular lever 26 which is fulcruuu-d at '37. The lever 26 carries a projection 28, which is normally arl ranged in the path of the coin 29 in a magazine 7. V j The lever 26 and projection 28 form one 4 member of the valve mechanism for conltrolling the discharge singly of the coins i from the magazine. The other member of this valve IHQChflIllSlH consists of the angular lever 30 fulcrumcd at 3], and having a projection 32 normally out of the path of the coin 29 but operable alternately with the projection 28. When projection 32 is pushed in, it engages in the perforation 33 in the magazine to intercept. the coin after the same has been dropped by the outward withdrawal of the projection 28. The other end of the lever 30 has an angular arm 34 arranged in the path of the angular arm 25 of the lever 26. A spring 35 arts normally to hold the arm 34- in operative contact with the arm 15. lly thus employing a lever 26 of the first class and a lever 30 of the third class and arranging themin the manner shown. l produce a. simultaneous actuation of both levers. but in opposite directions, whenrwr tlu pin 2 1- is pushed in to rock the lover arm .33. The valve members or i projections 28 are so spaced from each connections 21 between these several frames.

Those auroral i'rnnms 13 as shown in Figs. $1 and 2 are each capahlt-v of a limited indepcmlunt rocking n-iovcmei'it, hut they are all connected together in such fashion that they may be all siinnltancously rocked to the loft against the torision of their springs 22 to cal-r all tin.- pins out of tho path of the prossors 36 nnumtodwm the actuating bar 37.

The lover 40 is fulrrnnua] at 41-2 and is oporatvd on by the set koy 2. By pushing down on the key 2, lever 40 is rookod to rvliero the tension ontho Hprii'ign and allow all tho pins 24 to he brought into lino with the Dressers 3B.

I it will lit olisorrod that tho Hlllll total of all lllthtl romaining headings amounts to just $1. (All the keys 4 and 5 are pressed normally outward away from their respective levers 9 18 by means of the .-prings 4*. \Vhen any key is pushed in it is temporarily held in against the tension of its spring 4* by means of a spring-actuated rocking latch 4".) Having pushed in on the $1 ho. 4 key, and the same having been locked by its catch 4*, the operator next pushes in on certain of the N o. 5 keys to represent a total of 75, the amount of the pure iase. Ordinarily this 75 purchase would be indicated by the 50 key and the 25 key. Pushing in on the 50 and 25 keys of the No. 5 series, elfects a further diminution of the number of pins 24, which are in line with the pressers 36. As has just been said when the $1. of the amount receivedbank of keys 4 was )ushed in, there remained only $1s worth 0% with their pressers 36'; consequently, if the actuating bar 37 was rocked at that moment, only $1 in change would be delivered from the magazines. When the operator pushed in on the 50 and 25 keys of the No. 5 series or amount of sale bank, two more pins 24 were canried out-of the path of the actuators 36, leaving only 25 in change to be paid by the machine. (Of course instead of pushing in the 25 key of the N o. 5 bank, the operator could have pushed in the two 10 keys and the 59. key of this same bank with the same result.) Havin thus pushed in the proper keys of the two anks to represent respectively the amount received and the amount of sale, the change is paid out by the machine by the operator taking hold of the handle 6, which is connected to the actuating lever '45, and rock ing this lever to cause the actuators 36 to impinge on those pins 24 which are still in line with the actuators. As shown in Fig. 1 the lever 45 is rigidly connected to the bar 37, and the spring 46 acts to hold the actuators 3G in normally inoperative position with respect to the pins 24. lhe lever 45 has a projecting arm -17 to which the spring 46 connects. The lever 45 is engageable by a spring catch 48 to prevent the accidental or unauthorized operation of the machine. In order to operate the lever 45 it requires a slight outward pull. on the handle (3, which latter runs in the segmental slot 45) to release the lever 45 from the catch 48 and allow the lever 45 to he pushed back and rock the actuating bar 37. The movement. of the pivoted catch 48 is limited, and the actuating lever 45 is springv enough to allow it to be i'cleuscd From the catch when the handle (3 is pulled outward, as just explained.

If in making the change the operator has pushed in the wrong kcys,ihc latter together with all thel'iingod frames 13 can be throwii out of gear instantly, by actuating the repins 24 in line lease key 3, Fig. 1. This release key has its stem connected with the bar 50, Figs. 3 and 1.0, which is suitably mounted on swinging arms 50; for lengthwise reciprocation, and has a series of projections 51 corresponding each to a latch-member 4". The 5 ring 52, Fig. 3 and Fig. 10, acts on this re ease bar 50 to throw it'normally to the left out'of interference with the latch operations of the latches 4. Whenever a key as 4 or 5 Fig. 7, mshed in, the spring-actuatedlatch 4 will swing in behind the shoulder 8 or 20 of the respective stems 820 and hold the key in. lVhen the latches 4 are in this position, they abut against the projections 51 on the release bar 50. Consequently when bar 50 is pushed to the right, it will carr the latches 4 out of engagement with the ey stems and allow the keys to assume their normal outwardly pressed position. Thereleasing bar 50 is also adapted to be operated auti'nnatically --to release the keys 4 and 5 by suitable connections with the op erating lever 45. As here shown the lever 45 is connected by a normally slack chain 52 with a bell-crank-leve- 53 fulcrunied at 54 and connected by a link 55 with a lever 56. (Fig. 10).

The lever 56 is fulcrumed between its ends and carries. weight 57 at one end. A spring 58 acts on tlililever 5G to press the weight normally into contact with the left hand end of the releasing bar 50. When the lever 45 is moved back to rock the actuating bar 37, the hell-crank-lever 53 is rocked and one arm is carried back until. it is engaged by a dog 59, Fig. 4. At the same time the lever 56 is rocked" to carry the weight 57 away from the actuating bar 50. The latch 59 retains its hold on the lever 53 until nearly the completion of the return movement of the-actuating lever 45. About that time, and after the change has been released from the ma azines, a rod 60 carried by the arm 47 of ever 45 depresses the rear end of the latch 59 and releases the bell-crank 53, whereupon the spring 58 causes the wei ht 57 to strike a sharp blow on the releasm bar 50 and drive it to the right so that a the catches 4 will be released. At the same time the catch 44 (Figs. 1310) which holds the setting key 2 down is released from its hold on lever 40 by connections 44 with bar 50.

In order to insure a full swing of the actu ating lever i5 and give positiveness of action to the machine, the lever 45 carries a s n'ing-uciuuled pawl ll as shown in Fig. (i, which is adapted to ride free in one direction over a stationary rack 62 when the ac-,

, chine.

by any suitable means.

be returned until it reaches the full limit of its stroke in that direction.

When the coins are released from the magazines by the engagement of the pressers 36 with respective pins 524; which operation is effected by pushing back on the actuating lever 45 as just described, the coins strike on spring-actuated-flapdl'uunbers (it (Figs. 5 and 8) arranged in thepath of the falling coins, and these flap-members actuate corresponding semaphores (55, Fig. 5, which semaphores correctly represent the amount of money actually paid by the ma- These semaphores slide in suitable guides arranged just behind or in front of their respective magazines.

As is shown in Figsat'i and 8 the flapmembers (34 are mounted on a common fulcrum shaft 66, and each fla member 64 has an arm 66 connecting wit 1 a spring latch plate 67. Each semaphore 65 is adapted to be normally projected upward by a spring 68, and each semaphore carries an angular piece 69 at its lower end to which is attached one end of a cord 70-; the other end of this cord is connected to a spring-roller 71. This roller or drum 71, l igs. 3 and 4. has one end of a chain 72 wrapped around it, and the other'end of this chain is connected by a link 73 with the arm 47 of the actuating lever 45. Thus it will be seen that when the actuating lever 45 is pushed back to make change, the spring roller 71 is turned against the tension of its spring 75 to wind up the several cords 70 and pull down the semaphores until the angular pieces 69 on the semaphores are caught over the end of the spring-catch-plates 67, provided any of these spring-catchplates 67 have been lifted by the actuation of a valve or flap 64 on the falling of a coin. When the coin strikes a flap. it pulls out on the lower spring end of one of these springcatch-plates and allows the angular semaphore projection 69 to slide up behind it and cause its semaphore 65 to show above the top of the magazines.

The coins which are released from the magazines are delivered from the. machine I prefer to use a draper or endless belt 75', Figs. 3-4, running over the drums 7(' 77 and to give this draper an intermittent rotative movement through suitable conections with the actu ating lever 45. As here shown the drum 76 has a cord 77 wrapped around it in one direction with the end of this cord or chain connected with a suitably anchored spring 78. A' chain or cord 79 is wrapped around the shaft of the drum 7G in the opposite direction, and this chain passes around suitable direction pulleys 808l and connects to the actuating lever 45. \Vhen the actuating .leier is pushed back to pay out l change. the chain 79 turns the drapcr backwar againstthe ten ion of the spring 78.

iVith the draper thus on tension it is held in that position tel'nporarily by a. suitable brake mechanism consisting. as shown in Fig. 4, of an angular lever H 2 having a rubher or like so'l't head 3 which is adapted when the end of the lever is dropped to con-- 'tact with the head of the drum and temporarily prevent rotation of the drum under impulse oi the spring: TH. lho other end of the lever H2 has a loose connection 84 with a cross-head of a. piston 85 which acts in an air cylinder 86. This cross-head 85 is acted. on by a spring 87 which normally presses the piston S5 inward into the cylinder 86. The construction of this cylinder is such that the piston can move freely outward in the cylinder. but the inward movement of the piston under tension of the spring 87 is retarded by the compression of the air in the cylinder. This construction of pneumatic or fluid controlled device is so Well known as not to need further detail description. The piston 5 5 is also connected by a slack chain 88 with the actuating lever 45. When the lever 45 is pushed back to cause the machine to pay out. change, the piston 85 is pulled outward when the slack of the chain. 88 is taken up. This releases the slack on the connections 84 of the piston with the brake S2 and allows the latter under the tension of its spring 89 to fall so that the head engages the drum76, thus locking the drum against movement in one direction as has been explained. When the actuating lever 45 moves back again to initial position and after the change has dropped on to the draper, the piston 85 is allowed to retreat into the cylinder 86 as soon as the chain 88 slackens. It will be readily understood that with the drape! turned back and with the cord 77' wound up and the spring 78 on ten ion, that the moment that the brake 82 isrcleased, the draper will travel. in the direction of the pay chute 90 and deliver all the coins at once into this chute or pocket, Where they can be handed by the operator to the custumor.

In operation assume the machine to be in normal position ready to make change: The operator is handed in payment of 2:. 75 purchase. He first pushes down on key 2 to set the machine; i. e. to rock all the frames 13 and place the pins 24 in line with their respcctiy e actuators 36. He next pushes in the $1 key of the amount received series 4. This key by reason of its connecting links 21 with the rocker arms l111 &c. of the No. 4 amount received keys, marked $4, $5, $10, $20, will rock the frames 13 of these lastnamed keys to the left and carry their pins 524 out of the path of their corresponding actuators 36 on bar 37. \Vhen the $1 key above, was push d in engaged and held in by the catch 4". Next the operator pushes in the keys of the amount of sale or purchase series 5,- to the aggregate of the amount-of sale. Ordinarily he pushes in the 50 key and the 25 key of the amount of urchase series #5, and these keys are hel in by their respective catches 4". (If for any reason he has made a mis take 1n pushing in any of the keys of either series he simply throw: the machine out of gear and places all the parts in initial posi tion by pushing on the releasing key 3 which operates the release baiifiO to trip the latches 4*, or 4" or both according as both sets of keys 45 have been acted on, and to release the latch 44 to allow all the keys to return to normal. He then begins over again.) Pushing in on the 50 and 25 keys of the #5 purchase series as above described, cuts out the corresponding pins 24 by which delivery from the 50 and 25 magazines is controlled.

\Vhile the amount received keys 4 are coupled up in accordance with their several monetary values so that under no circumstances can a sum be paid out in excess of the amount represented by the punched keys of this series, the amountof purchase keys are adapted individually in most instances to act only on a single actuator pin 24 and so cut out an individual. magazine: each time a key 5 is punched it subtracts just so much from the amount represented by the punched amount received keys 4. The operator next takes hold of the handle 6 of the actuating lever 45, pulls it out a little so as to disengage the latch 48 and then pushes back on the lever to rock the actuating bar 37 and cause the actuators 36 to engage such of the pins 24 as have not been previously moved out of line with the actu ators. These remaining pins 24 which are now acted on are only those belonging to the we magazine and the three 59$ magazines and as only a single coin can be de- Iivened from any magazine by one actuation of lever 45, it is manifest that only 25 will be paid from these four magazines. The actuation of lever 45 to rock the bar 37 causes the pins 24 of these four magazines to move back and to operate the valve levers 26-30 (Figs. 7 and 5): when valve members 28-32 reverse their positions shown in Fig. 7 and assume their position indicated in Fig. 5, the coin drops onto valve member 32. When the pressure on the pin 24 Fig. 5 is relieved, the members 32--28 change positions again back to that of Fig. 7. and the coin drops onto the draper 75. Meanwhile the draper has been turned to put its spring 78 on tension and locked temporarily in that position by the brake 82-83. hen the lever 45 comes back to initial position and after suflicient time has elapsed for the coins to fall from their magazines onto the draper,

, or keys $5 and $3 may the brake is released and the draper runs forward to deposit all the coins which are on it, into the pocket 90. The amount so deerul latches 4, 4 and 44, to allow the several keys 4-5-2 to resume their normal position. The hammer 57 (Fig. 10) may in the act of operating the bar 50, actuate a bell 91 by means of the clapper 92 carried by lever 56, for the purpose of giving an audible signal to show the operation of or tampering with the machine. The coins when they are dropped from the magazines onto the draper,

strike the flaps 64 and release the semaphores 65 of those magazines paying out coin. Thus in the illustration above of payin 25 in change the 10 semaphore an the three 51 semaphores are elevated to show to the customer and the operator just the amount of change actually paid out. These semaphores are depressed again into inoperative position on the return of the actuating lever 45 by the Winding up of the cords" on the roller 71 as previously described.

Among the favorable features of this machine are to be noted the followin The paying of change being mechanical t e machine cannot pay wrong if the amounts received and amount of purchase are punched correctly. he machine cannot be operated at all unless the handle 6 is first pulled to the right which unlocks lever 45. The machine will not pay change unless the setting key 2 is punched, but the handle will Work and ring the bell. The machine indicates the amount of change actually paid out, and not the amount it should pay, unless it actually pays that amount. If it pays short, it indicates short as seen by the semaphores; and if it pays over, it registers over. Thus the actual amount received by the customer is accurately told by the machine, which is an important feature should there be a dispute over change. Change for any denomination can be made, Within the limits of the machine by simply pushing the button in the amount received'bank, and the setting key 2. and then working the lever .45. Amounts of 10-25-50-$1-$5-$10 and $20 must be punched by their corresponding amount received key; but amounts for which there is no single key may be punched by any combination of keys, viz: If $7 is the amount to be punched, keys $5 and $2 or keys $4 and $3: if $8 is the amount, keys $5. $2 and $1, 7 be used. Change can be paid out'in the largest denomination possible, or may be paid out in small denomination at the will of the operator. If by chance a piece of money should stick in machine, it registers that amount short, which can be seen at a glance by reference to the semaphores. Money when received can elther be dropped 11] slots in the magazines or into a drawer as 93 at the bottom of machine through slot 94 (Fig. 1). If it is noticed that the machine is getting short of a particular denomination money as received, can be dropped into that magazine. At night when it is desired to remove money from the machine it can be done in a second by pulling a lever 95 which rocks a'bar ht Figs. 4 5 7, on which all the valve levers 26-30 are mounted: This has the effect of removing all the valve members 28-432 out of the path of the incumbent columns of coins so that all the money in the magazines falls on to the draper. Mistakes can not be made in counting out change, or reckoning change by the machine, provided the right keys are punched. If the wrong keys are ac cidentally punched, they can be released by the key 3 especially designed for that pur pose; whereupon the right ones can be punched over again.

.It is possible that various changes and modifications maybe made in the invention without departing from the principle thereof.
